Application filed May 22, 1917. Serial No. 170,26.

ing description and falling within the scope of the appended claim.

lr. the drawing:

Figure 1 is a perspective view of a tool constructed in accordance with the present invention,

Fig. :2 is a top plan view' of the saine,

l-"ig. 3 is a sectional view approximately on the line 3-3 of Fig. l, and y Fig. Je is a sectional view approximately onA the line -t-l of Fig. l. 1

i is a sectional view approximately on the line of Fig. 1,

In the present construction of such tools employed for extracting cotter pins or keys which have come under my observation, from experience, I have found that the same are not properly constructed to permit of the free operation thereof, especially in extracting or removing the keys emplojyved in connection witli'castellated nuts,which class of nuts are now commonly employed in connection with automobileconstructions and other machinery work. It may be therefore considered the primary objectof the present invention to con struct a tool-of this Character wherein the A eye portion of the cotter pin may be readily engaged even when wholly received in the slots upon the face of a castellated nut and also whereby the tool is readily fulcrunied upon the nut to permit of the free extraction of the key when the same is so positionedV that only a small space is required in which to manipulate the tool.

The device, as illustrated by the drawings, comprises two pivoted levers 1 and Q respectively, the pivot being prefe'ably in the nature of a headed stud 3 secured to one of the sides of the member 1 and having its shank received in an elongated slot t in the other lever 2. Tte-lever Q,- beyond the pivot 3 comprises what l term a jaw and the said jaw may be formed upon its inner face with a knife extension G and the outer endof the said jawis arranged angularly or, at

a curvature with respectto the longitudinal plane of the lever :2 and terminates inA a beak AT. This beak has its' outer end, of course,

terminating in a point and is rounded to its connection with the Jaw proper.

The portion of the lever' 1, beyond thepivot 3, also provides what I will term. a-jaw said jaw having its inner faeef'str'aightand, when the Jaw 5 is provided with the knife,

formed with ya slot 9 to receive the knife member 6 of the jaw o.

which the pointed end of the beak 7 is adapted to pass. The outer face of the portion 10 is conc-aved from the end thereof, as indicated by tlie numeral 12, yand is rounded, as at 13, tothe lower edge of the jaw proper` the said eoncaved portion 1:2 providing the outer end of the jaw 8 with a knife pointlle, and the concaved portion 12 provides one of the fulcrum elements of the tool, the rounded or convex portion 13 providing another fulcrum point, and the roundedouter ysurface of the beak l' providing .still another fulcruin point. The end of the lever 1 may be and is preferably sharpened, as'at 15, and this sharpened end when inserted between the limbs of a cottei key or pin'provides for the ready se Jaration o r sprea of the said means fv vhile.the knife finenf e 6 permits of the 'cutting of the liinbsi hejkey or pin, when "itis found that the? is of a greater length than requiiec.

From the foregoing when take nection with the drawings, it will; e noted by those skilled in the art to which such iiivention appertans, that the beak being rounded angularly away frmithe jaw and in the direction ofthe beak, terminating in the sharpened point 1l, permits ofthe i The straight inner; .face at the outer portion thereof is stepped, as at 10. and this stepped portion iS gradu tool engaging with the eotter pins arrangeds in a comparatively small space for the op' eration of the tool and that theqtgnl memes 1 receive a, fuloruin bearing t almost any ongle with respect to the bea-k and nose.

Hai-ving thus described the invention, what I claim is:

A tool for the purpose set ortlrcolnprs- 'ing two pivotallyjconneeted 'levers `formed each with a jaw'otward ofthe pivotal oonnection between the levers, both of said jaws being arranged at an'outward single in the 10 same direction from the' Vrespective leversv downturned beak, the I(ingle end of the 'other jaw having an opening to receive the beak,

and a pointed nose on one of the corners ofl the seid end of the referred to last mentioned jaw.

In testimony whereof I alx my signature. i
